PC MAINTENANCE CHECKLIST

Use these checks regularly, when needed or after relevant updates. Every PC and environment is different.

Inspect and clean accessible dust filters when dust begins to build up.
Check CPU and GPU temperatures when performance, noise or stability changes.
Install graphics drivers when a relevant update or game requires one.
Keep useful free storage space and remove files you no longer need.
Install appropriate Windows and security updates, then confirm the PC remains stable.
Back up important files before major changes or troubleshooting.
